reto
/ˈreto/ · B1 · noun · m
challenge
🥊 reto sounds like retort: a sharp reply that throws down a dare
From the verb retar (to challenge, to dare), which goes back to Latin reputare via Old French reter, to accuse. A retort and a reto both answer someone with a challenge, so the word covers a dare, a scolding and an insult too.
